I'm trying to learn it now, beside JS, to work on modding some apps. But I've seen that it's not that popular nowadays, even though it's very useful for that end.

What's your opinion on the language? Should I be using some other language for modding apps? Do you like it?

It was one of the first languages I learnt so I really enjoy coding in it. It's very versatile and there is a lot of programs that still use it, being one of the prominent languages in modding. I think is a good mix between JS and Python, but that's a personal point of view.
